Dec. 25 is looming — which means it’s officially that time of year during which one cannot walk down a street block without being assaulted by the sound of Mariah Carey singing “All I Want For Christmas Is You.”

Wednesday night, the holiday classic endured as Carey performed the tune on NBC’s “Christmas in Rockefeller Center” special — but this time, Carey didn’t so much kill the song as she did the crowd’s ears.

After missing her planned pre-taped segment the day before, Carey performed the perennial hit live during the show — only without any of the high notes. Adding to the mess were child back-up dancers seemingly dancing to a hip-hop song that was not playing.
